Gastroscopy and Colonoscopy: Traditional or Pain-Free?

As a gastrointestinal surgeon, I frequently encounter patients who require endoscopic examinations to confirm or rule out certain conditions. In recent years, many patients have specifically requested pain-free endoscopic procedures. However, I often recommend the traditional method. So, which one is better? Let me share my perspective.

What Are the Advantages of Pain-Free Endoscopy Compared to Traditional Methods?

Pain-free gastroscopy and colonoscopy involve the use of intravenous sedation, allowing patients to undergo the procedure in a relaxed and comfortable state. The most notable benefit is the elimination of discomfort and anxiety during the examination. This can lead to better patient cooperation and a smoother, more thorough examination for the physician. It's no wonder that many patients prefer this option.

Are There Any Drawbacks to Pain-Free Endoscopy?

Despite its advantages, pain-free endoscopy is not without controversy. One concern is that it removes the natural pain feedback mechanism, which can be an important guide for the endoscopist. In traditional endoscopy, local anesthetics and lubricants are typically applied, and most patients can tolerate the procedure without full sedation. Pain during traditional endoscopy often signals that the scope has reached a bend or sensitive area in the digestive tract, prompting the doctor to adjust technique and avoid complications such as perforation. With pain-free methods, this feedback is lost, potentially increasing the risk of complications. Additionally, sedation carries its own risks, particularly for patients with cardiovascular conditions or other health issues.

How Should Patients Decide Between Traditional and Pain-Free Methods?

From a clinical standpoint, traditional endoscopy is often the preferred option, especially when urgent diagnosis is needed. For example, if a patient presents with symptoms such as dark or black stools, changes in bowel habits, abdominal masses, or elevated tumor markers, early diagnosis of conditions like gastric or colorectal cancer is crucial. Traditional endoscopy typically allows for quicker scheduling and avoids the additional time required for anesthesia and recovery. Furthermore, it places fewer demands on the medical team in terms of technical expertise and monitoring.

On the other hand, for routine health screenings or for patients who are particularly anxious or sensitive, pain-free endoscopy can be a valuable alternative. Ultimately, the choice should be based on individual needs, medical history, and the recommendation of the physician.
